10. Commandos: Behind Enemy Lines

Commandos: Behind Enemy Lines is a real-time action game that lets you employ six Allied commandos in the dangerous art of small-unit tactics. That is, you’re controlling (in an isometric top-down view) six battle-hardened veterans to sabotage and assassinate Nazi positions in order to retrieve information or rescue POWs. Each unit has its own set of skills (from explosives and sniping to stealth and diving), and lets the player strategize on their Nazi-killing scheme based on enemy behavior. The game spawned four sequels and a number of improvements (including using “hotkeys”), but the original is still the best.
